8 Claims.

This application is a continuation-impart of my application, Serial No. 181,877, filed December 27, 1937, which latter is a continuation-in-part of my application, Serial No. 710,859, iiled Feb- 5 ruary l2, 1934.

The rug of the present invention is in the main composed preferably of ber which in the language of the trade refers to a strand of twisted strips of paper in the form of paper twine. The

l fiber is of soft and pliable material well adapted for the making of relatively cheap rugs, in that the fiber strands can be closely packed together,

or beaten up in the loom, but :liber rugs possess one disadvantage, in that the colors employed are i relatively non-fast and somewhat dull in tone,

so that a rug composed of fiber not only lacks sharp color tones in the rst instance but tends after usage to become dull and dingy and to lose its appearance of newness or freshness after a comparatively short period of wear.

The object of the present invention is to compensate for these defects by the employment of conspicuously arranged strands oi sisal which are intended to brighten up the general effect of the rug as a wholeand to compensate against early deterioration in the general appearance of the rug due to the fading of the colors employed in the fiber background.

With these ends in view, the invention consists in the employment of relatively thick or conspicuous sisal strands both in the warp and in the woof or filler, which not only display fast colors but present a lustrous effect and an intensity of coloration which it is impossible to obtain with the fiber alone.

In the employment of 'sisal strands, however, I have found by experience that diiiiculties are involved in the use of a. considerable amount of sisal in the warp and also in the Woof, by reason 40 of the character of the sisal which is a stiff wiry fiber which is difcult to compact within the loom, and this difliculty is greatly enhanced in cases where strands of sisal are used both in the warp and the woof, thereby introducing areas where the sisal strands intersect one another, which thus constitute points at which there is a tendency for the rug to warp or buckle.

In order to effectively use the sisal in both the warp and the Woof of the rug it is essential to use the sisal somewhat sparingly, with wide intervening areas of fiber both in the warp and the Woof, so that the ilber will serve to compact and anchor the sisal strands firmlyin place, particularly at or near the points of intersection, so that Vg the warping or buckling tendency will be overcome, particularly when the rug is exposed to dampness or variable weather conditions.

I have found that very effective use may -be made of the lustrous sisal strands, both in the warp and in the woof, by employing for each sisal stripe one or two strands of conspicuously greater bulk than the intervening lber strands, so that the sisal will be conspicuously displayed not only by its lustrous color but by its greater spread and contrast inV appearance to the more closely woven fiber strands which compose the major portion of the rug body.

I have also found that where one or two bulky sisal strands (or at any rate a very limited number) are employed both in the warp and in the woof, the areas at the points of intersection are suniciently reduced in extent, so that warping or buckling in the form of ridges or humps is prevented by the close anchoring of the sisal strands at these points of intersection; but experience has shown that where the intersecting areas are of as great an extent as three or four inches square within which the fabric of the rug is exclusively or mainly of sisal, difficulty is experienced by reason of the impossibility of anchoring the sisal strands throughout such an extended area and in such a way as to prevent bulging or buckling. Experience has shown, however, that where the areas of intersection of the sisal warp and Woof strands do not exceed two inches square, the constituent warp and woof stripes thus afforded may be composed exclusively or mainly of sisal with the rpossible interspersion of va few fiber strands.

While some slight latitude is permissible in the quantity of sisal present at the points of intersection oi the warp and Woof, I have found that the most certain and reliable results are obtained where not more than two or possibly three bulky sisal strands are grouped to afford a conspicuous warp stripe in conjunction with a like arrangement of sisal strands in the woof, thereby reducing the areas of intersection to about an inch square where such a group arrangement is employed.

However, I have also found that the additional use of single strands of bulky sisal interspersed through the fiber warp and Woof may be advantageously employed in conjunction with multiple strands, so that a considerable display of sisal will be afforded throughout the` rug, without, however, concentrating the sisal at any one point to an extent which will preclude its firm anchorage into the more pliable and compactible fiber.

I have also found that by dip dyeing the sisal strands in fast colors in those sections of each skein which are immersed in the dye, and by alternating the sections of strands so dyed with sections which display the permanent silvery lustrous color of the natural sisal, highly eilective results can be secured in providing a variegated display in permanent `colors or lusters which are more conspicuous in appearance than the surrounding areas aiiorded by the duller and less permanent color tones ofthe fiber, so that after usage for a considerable period the rug will retain a fresh and pleasing appearance even though the less permanent dyes employed inthe `fiber have lost their original intensity. In this way, by the somewhat sparing use of sisal in interspersed relation to a much greater volume ofnber, it is possible to successfully employ the sisal and to obtain the highly desirable color effects characteristic of the materialwithout im, pairing the quality oi the fabric or introducing alfactor which if otherwise uncontrolled would tend in a short time to cause such excessive warping or buckling as to render the rug uniit for service.

In order to more fully bring out the features above described as incorporated in` a rug of proved value and excellence in character, reference is had to the accompanying drawing, wherein,-

Figure `l is a plan view of. a corner of a rug partly finished to illustrate the speciiic weave of the fiber and sisal strands, with the remainder of the figure illustrating a continuation of the same characteristic weaving;' and Pig. 2 is a section taken on line 2-2 of Fig. l.

The rug as a whole consists in the main of interwoven ber warp strands A and wool strands B, which are preferably of relatively small thick- .ness or diameter as compared with the sisal strands .presently to be described. As shown, the method of weaving the warp and woof ber strands comprising the predominant area of the rug` is one which gives a ribbed effect, and the strands being pliable and compactible are closely interwoven with one another.

At recurrent intervals in the body of the rug are sisal warp stripes which may be afforded by two or slightly more strands C bundled together `in groupzrelation with intervening single sisal warp strands D. As shown, `the sisal strands are much heavierLsingly than the warp and woot ber strands, and when united in groups of two or slightly more afford a very conspicuous contrast to the fiber body of the rug, not only by the greater'bulk of the individual sisal strands but by reason of the permanent lustrous color tones afforded either by the display of the natural sisal or by the intense colors aorded by dip dyeing recurrent portions oi each sisal strand.

In like manner, Woof strands of sisal are employed either in limited group arrangement as at E or singly as at E', it beingunderstood, however. that in all cases the warp and wool strands, whether employed singly or in limited group arrangement, are anchored and imbedded within the surrounding ilber, which in quantity greatly exceeds the amount of sisal employed.

At the `points of intersection F, where the grouped warp and sisal strands cross one another, the resultant thickness of the rug is necesl sariiy increased in cases where bulky sisal strands are employed, and it is at thesepoints that it becomes highly essential to restrict the area of intersection suillciently to enable the surarcanos rounding `fiber strands to aii'ord a sumciently firm grip andcompression upon the sisal to prevent working or slipping of the `sisal strands which if the ares of intersection be materially extended will result in a warping or bulging elfect at these points when the rug is subjected to atmospheric variations. By utilizing a limited amount of sisal in substantially the manner above described, or at any rate in a restricted amount conformable to the principles of the present invention, it is possible to secure highly .satisfactory results both in the structure of the rug and 'in its coloration and to secure the freshness and permanent luster afforded by the sisal without sacriiicefof those qualities in the rug structure which are essential.

Although the present description is intended to substantially indicate the limits within which the permanently dyed sisal may be employed for brightening up or improving the quality and appearance of a rug mainly composed of liber, it will be understood that, within the limits stated, numerous highly eiiective designs can be developed and that the drawings serve merely for the purpose of illustrating the principle of the present invention as applied to a rug which has proven highly successful, both in coloration and in wearing qualities.`

It will also be understood that although bulky sisal strands singly or in very limited group arrangement serve to present a satisfactory and conspicuous display of the lustrous sisal, nevertireless the use of groups of sisal strands of lesser bulkindividually but of greater number may in proper cases be employed if the areas of intersection are limited in extent and the sisal strands are closely anchored and compacted by the surrounding liber.
